示例1: printf
/*!
This method appends all the class types derived from \a type to \a list,
and returns the number of types added to the list. Internal types are not
included in the list, nor are they counted.
\a type itself is also added to the list, as a type is seen as a derivation
of its own type.
NB: do not write code which depends in any way on the order of the
elements returned in \a list.
Here is a small, stand-alone example which shows how this method can
be used for introspection, listing all subclasses of the SoBase
superclass:
\code
#include <stdio.h>
#include <Inventor/SoDB.h>
#include <Inventor/lists/SoTypeList.h>
static void
list_subtypes(SoType t, unsigned int indent = 0)
{
SoTypeList tl;
SoType::getAllDerivedFrom(t, tl);
for (unsigned int i=0; i < indent; i++) { printf(" "); }
printf("%s\n", t.getName().getString());
indent++;
for (int j=0; j < tl.getLength(); j++) {
if (tl[j].getParent() == t) { // only interested in direct descendents
list_subtypes(tl[j], indent);
}
}
}
int
main(void)
{
SoDB::init();
list_subtypes(SoType::fromName("SoBase"));
return 0;
}
\endcode
*/
int
SoType::getAllDerivedFrom(const SoType type, SoTypeList & list)
{
assert(type != SoType::badType() && "argument is badType()");
int counter = 0;
int n = SoType::typedatalist->getLength();
for (int i = 0; i < n; i++) {
if ((*SoType::typedatalist)[i]) {
SoType chktype = (*SoType::typedatalist)[i]->type;
if (!chktype.isInternal() && chktype.isDerivedFrom(type)) {
list.append(chktype);
counter++;
}
}
}
return counter;
}
